The tortoise can walk 3/5 of a mile in 1/2 of an hour. How many miles can he walk in 1 hour?
How do you think you can solve this problem?
To find out how many miles the tortoise can walk in 1 hour, we can set up a proportion using the given information.
Let's represent the distance the tortoise can walk in 1 hour as "x".
We know that the tortoise can walk 3/5 of a mile in 1/2 of an hour. So we have the following proportion:
(3/5) miles / (1/2) hour = x miles / 1 hour
To solve for x, we can cross-multiply and solve for x:
(3/5) * 1 hour = x miles * (1/2) hour
The hour units cancel out, leaving us with:
3/5 = x * (1/2)
Now, let's solve for x by multiplying both sides of the equation by 2/1 (to cancel out the 1/2):
(3/5) * (2/1) = x * (1/2) * (2/1)
6/5 = x
So, the tortoise can walk 6/5 miles in 1 hour, which simplifies to 1 1/5 miles or 1.2 miles.
Therefore, the tortoise can walk 1.2 miles in 1 hour.
